FOLDING DELIVERY.

To all whom it may concern:

Be it known that I, ELLIS W. COOPER, a citizen of the United States,residing at Bloomfield, county of Essex, and State of New Jersey, haveinvented certain new and useful Improvements in Folding Deliveries,fully described and represented in the following specification and theaccompanying drawings, forming a part of the same.

This invention relates to certain improvements in folding deliveries.

Folding deliveries of a certain class comprise a rotating sheet carrierprovided with grippers or similar devices for seizing the leading edgeof the sheet and forwarding the same, a tucking blade, and a secondrotary carrier provided with nipping jaws into which the tucking bladetucks the sheet in order to fold it 01f. WVhere such a delivery isconstructed to fold off different sizes of sheets, it is necessary tomake the tucking blade adjustable circumferentially of the cylinder, sothat no matter what the size of the sheet may be, the tucking blade willoccupy the proper relative position with respect to the grippers toimpart the desired fold to the sheet. This circumferential adjustment ofthe tucking blade, however, requires a corresponding circumferentialadjustment of the nipping jaws in order that the relation between theblade and jaws may not be disturbed, and also requires an adjustment ofthe means for operating the grippers, so that the grippers may releasethe sheet at the time the tucking action ocours.

It is one of the objects of this invention to produce an improvedfolding delivery embodying a rotating carrier provided with devices forholding the leading edge of the sheet, and a tucking blade which tucksinto nipping jaws on a second rotary carrier; the construction beingsuch that a circumferential adjustment of the tucking blade with respectto the sheet holding devices also effects a corresponding adjustment ofthe nipping jaws so that the relation between the two is not disturbed.

A further object of the invention is to produce an improved deliverymechanism embodying a rotary sheet carrier provided with holding devicesfor the leading edge of the sheet and a tucking blade, and a ro-Specification of Letters Patent.

tating carrier provided with nipping jaws, the construction being suchthat a circumferential adjustment of the tucking blade with respect tothe sheet edge holding devices produces a corresponding adjustment ofthe nipping jaws, and also simultaneously therewith adjusts the meansfor operating the sheet holding devices, so that they will release at.the proper time.

lVith these and other objects not specifically referred to in view, theinvention consists in certain constructions and in certain parts,improvements and combinations as will be hereinafter fully described andthen specifically pointed out.

Referring to the accompanying drawings which illustrate so much of adelivery mechanism as is necessary to an understanding of theinvention-Figure 1 is an end elevation of a delivery mechanism embodyingthe invention. Fig. 2 is a plan View of the construction shown in Fig. 1so far as it relates to the folding mechanism.

Machines embodying the invention will include a rotary carrier providedwith suitable devices for taking the leading edge of the sheet. In theparticular construction illustrated, the rotary carrier, indicated at 1,is mounted on a shaft 2 provided with a driving gear 3, said shaft beingmounted in the frame. The bearings for the shaft are indicated by bosses4. In the particular construction illustrated, the devices for seizingthe edge of the sheet comprise grippers 5 mounted on a shaft 6 supportedand free to turn in arms 7. These arms are supported and fast on anoperating shaft 8 journaled at one end in one of the heads 9 of thecylinder, and at its other end in a boss 10 fast in the other cylinderhead 11. The end of the shaft is provided with an operating arm 12 whichworks in a groove 13 (see Fig. 1) in a closed cam 14. 14 surrounds theshaft 2 loosely and is supported by another cam 15, this cam beingsecured to the frame by bolts 16 tapped into bosses 17. The function ofthis cam 15 will be explained hereafter. The boss 10 is provided with agear 18 with which meshes a pinion 19 on the gripper shaft 6. Theconstruction is such that as the shaft 8 is rocked the shaft 6 bothmoves around the axis of the shaft 8 and also turns around This cam itsown axis. This construction of gripper is a well-known one, and anyother suitable construction may be substituted therefor.

The sheets may be supplied to the grippers 5 in any suitable way. Asshown, they are taken from a platform moimted on crossbars 20, thesheets being deposited on this platform by a traveling carriercomprising chains 21 and grippers 22. As the sheets may be delivered tothe grippers 5 in any suitable way, the particular construction of thetraveling carrier and platform has no special reference to the presentinvention and no further description or illustration of it will begiven.

Machines embodying the invention will include a tucker blade which maybe variously constructed, and a suitable support for the blade. In theparticular machine illustrated, the support for the tucker bladecomprises heads 23 secured to the heads 9 and 11 of the cylinder bybolts 24, the heads 23 being provided with slots 25, so that they may becircumferentially adjusted with respect to the ends of the sheetcarrier. The cylinder has its periphery recessed as shown by dottedlines in Fig. 1, to permit this adjustment. In the constructionillustrated, the sheet carrier is provided with two sets of grippers 5,and, therefore, with two tucking blades, one for each set of grippers.The tucker illustrated is of the rocking variety, the blade, indicatedat 26, being mounted on a shaft 27 journaled in the heads 23. The shaft27 is provided with an operating arm 28 carrying a roll 29, this rollrunning on the face of the cam 15. Constructions embodying the inventionwill also include a pair of nipping jaws, and as usual in suchconstructions these nipping jaws, marked 30, will be mounted on a rotarycarrier 31 which is supported on a shaft 32. These nipping jaws areoperated from an arm 33 which runs on a stationary cam 34 supported on abracket 35. This construction of nipping aws is a common one in the artand further description. of them is unnecessary.

It will be understood that by loosening the screws 24 the heads 23 whichform the support for the tucker blades may be circumferentially adjustedabout the shaft 2, and that this adjustment changes the relativeposition of the tucker blade with respect to the grippers 5, so as toproduce a fold of greater or less width, as may be desired.

In machines embodying the invention the construction will be such thatwhen the tucker blades are adjusted as described, the nipping jaws willbe correspondingly adjusted so as to avoid disturbing the necessaryrelation between the jaws and the blade. While this adjustment may beeffected in various ways, in the particular construction illustrated,one of the heads 23 is provided with a boss 36 to which is fast a gear37 which meshes with a gear 38 fast on the shaft 32 which is the shaftof the rotary nipping jaw carrier. lVhen, therefore, the heads 23 areadjusted circumferentially, there will be a correspondingcircumferential adjustment of the nipping jaw carrier, so that therelative position of the aws and tucker blade are not disturbed. It maybe remarked that the heads 23 are tied together by two braces 39. Thesebraces are ribbed and terminate in feet, the outline of which isindicated by dotted line 40 (see Fig. 1). The feet are secured to theinner sides of the heads 23 by screws 41. This construction of bracegives special strength to the construction. The heads 9, 1O of'the:rotary carrier are provided with slots, the outline of which isindicated by the dotted line 42, to permit the circumferentialadjustment referred to. hen the tucking blade and nipping jaws arecircumferentially adjusted, the time at which the grippers operate torelease the sheet must be changed accordingly. In machines which embodythe invention in its best form, the construction will be such that thechange in time of operation of the grippers to release the sheet will beeffected simultaneously with the adjustment of the tucker blade andnipping jaws. IVhile the means by which this is effected may be varied,in the particular construction illustrated, the shaft 32, which is theshaft on which the nipping jaw carrier is mounted, is provided with anactuator in the form of a cam 43 provided with a groove 44 (see dottedlines in Fig.1). The operation of the grippers to release the sheet iseffected by means of a latch 45 '(see Fig. 1) fixed on a short shaft 46which passes through and is j ournaled in the cam disk 15. In its normalposition, this latch 45 forms a part of the outer wall of the groove 13which is the groove which actuates the arm 12 of the gripper operatingshaft 8. The shaft 46 has an operating arm 47 connected to it, this armbeing in turn connected to a forked rod 48, the end of this rodstraddling the shaft 32. This forked rod has an anti-friction roll 49fast therein which runs in the groove 44 of the cam 43. In the operationof the mechanism the forked rod is operated by the cam groove 41 so asto swing the latch 45 outward on its pivot 46. This releases thepressure on the anti-friction roll on the arm 12 of the gripperoperating shaft and allows the same to swing so as to release the sheet,the sheet at this time having its fold tucked into and held by thenipping jaws. Since the cam 43 is fast on the shaft 32 anycircumferential adjustment of the tucker blade and nipping jaws willeffect a corre sponding adjustment of the actuator cam.

A holding roll, as 50, may be employed in connection with the nipping awcarrier, as usual in such constructions, and the carrier may be providedwith grooves, as 51, engaged by a stripper, indicated at 52, to assistin delivering the sheet therefrom.

Changes and variations may be made in the construction by which theinvention claimed is carried into effect. The invention claimed,therefore, is not to be confined to the particular construction hereindescribed and illustrated in the accompanying drawings.

What is claimed is:

1. In a folding delivery, the combination with a rotary sheet carrierhaving holding devices for the leading edge of the sheet and a tuckingblade, of a second rotary carrier provided with nipping jaws cooperatingwith the tucking blade, means for operating the holding devices torelease the sheet, and means for simultaneously adjusting the positionof the tucking blade with respect to the edge holding devices, theposition of the nipping jaws with respect to the tucking blade, and theholding device operating means.
